some issues configuring openbsc

While I think I am pretty close to getting my ip.access nanoBTS to communicate with my laptop running osmo-nitb I seem to be running into a problem. I am running openbsc-0.9.13 and using libosmocore-0.1.30 When I start osmo-nitb I see this error: ./osmo-nitb -T -c ./openbsc.cfg DB: Database initialized. DB: Database prepared.

That is fatal. Was the bts type and frequency properly specified? I am using one of the stock nitb configuration files with no modifications. openbsc.git/openbsc/doc/examples/osmo-nitb/nanobts/openbsc.cfg My setup is a little odd. I did not do the original configuration for the nanoBTS. I was hoping to just get stuff working with the current configuration before I changed anything. The nanoBTS comes up with an IP of 2.2.2.1 and expects a gateway of 2.2.2.2. So I simply configured the ip eth0 on my laptop to 2.2.2.2. Then annoyingly the nanoBTS starts looking for 3.3.3.3. Now I start getting a little hacky to try and move stuff along: ip addr add 3.3.3.3/24 dev eth0 ip route add 3.3.3.3/32 via 2.2.2.2 I am able to use ipaccess-find: ./ipaccess-find eth0 # finally shows # MAC Address='00:02:95:00:51:83' IP Address='2.2.2.1' Unit ID='1801/0/0' # Location 1='' Location 2='BTS_NBT131G' Equipment Version='165b029_58' # Software Version='168a302_v142b13d0' Unit Name='nbts-00-02-95-00-51-83' # Serial Number='00106317' I am also able to use ipaccess-config: ./ipaccess-config -u 1801/0/0 -o 2.2.2.2 -r 2.2.2.1 # Trying to connect to ip.access BTS ... # <0005> abis_nm.c:537 OC=SITE-MANAGER(00) INST=(ff,ff,ff) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) # <0005> abis_nm.c:537 OC=BTS(01) INST=(00,ff,ff) STATE CHG: OP_STATE=Disabled # AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=BASEBAND-TRANSCEIVER(04) INST=(00,00,ff) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # OML link established using TRX 0 # setting Unit ID to '1801/0/0' # setting primary OML link IP to '2.2.2.2' # <0005> abis_nm.c:537 OC=CHANNEL(03) INST=(00,00,00) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=CHANNEL(03) INST=(00,00,01) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=CHANNEL(03) INST=(00,00,02) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=CHANNEL(03) INST=(00,00,03) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=CHANNEL(03) INST=(00,00,04) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=CHANNEL(03) INST=(00,00,05) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=CHANNEL(03) INST=(00,00,06) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=CHANNEL(03) INST=(00,00,07) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=RADIO-CARRIER(02) INST=(00,00,ff) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=GPRS-NSE(f0) INST=(00,ff,ff) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=GPRS-CELL(f1) INST=(00,00,ff) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=GPRS-NSVC(f2) INST=(00,00,ff) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=GPRS-NSVC(f2) INST=(00,01,ff) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=BASEBAND-TRANSCEIVER(04) INST=(00,00,ff) # IPACCESS(0xf0): SET NVATTR ACK # Set the NV Attributes. # The BTS has acked the restart. Exiting. At this point I try to start osmo-nitb and receive the error I mentioned earlier: ./osmo-nitb -T -c ./openbsc.cfg DB: Database initialized. DB: Database prepared.

That is fatal. Was the bts type and frequency properly specified? I think the bts type is set correct in the configuration file: type nanobts I am not sure what setting actually sets the frequency. I am happy to provide more information and any help is appreciated. Thanks in advance, -Steve
